I'm especially interested in the timing of videos/photos in which the guy is carrying the cross-body bag and those in which he was not. I think someone said that they were figuring out whether he could've been carrying the bag under his jacket.
In the video with him wearing the cross-body bag, his belly appears to completely fill his jacket. So I'm not sure how he could get the bag under it. In the photos without the bag, it also doesn't look to me like he slung it over his back under the jacket. So my guess is that he stashed the bag somewhere, depending on the timing.
(In some videos he looks fatter than in others, but that might come from the angle. I think his belly looks big in the photo with the cross-body bag, but doubt that he was carrying anything else under his jacket.)
If the bag contained his gun, another question is of course what he did with it. More obvious questions -- did he take it with him? Where did he go?
Someone in the presser just said something about photos before and after the shooting. Have they released any photos from after the shooting, or did the LE person misspeak?

ETA: Of course, it's possible that at times he was carrying the bag under his jacket. It just didn't look like that to me.
